This analysis explores the physics concepts of momentum and rotational motion as depicted in a scene from "Pirates of the Caribbean," featuring William Turner (Orlando Bloom) and Joshamee Gibbs (Kevin McNally). Trapped within bone cages, the crew swings over a cliff to escape. We estimate key physics values: the distance between cliffs (27.9 m), rope length (23.65 m), and cage weight (477.5 kg). The swing duration is calculated at 12.9 seconds, considering air resistance, showing practical applications of physics in action-adventure cinema.

Physics Concepts • Momentum • Rotational motion
Scene • William Turner played by Orlando Bloom • JoshameeGibs played by Kevin McNally • Will and the rest of Captain Jack Sparrows crew are trapped within cages that are made of the bone of the rest of the crew • They swing over to the side of the cliff in order to climb up it

Estimated Values • Distance between cliffs: 27.9 m • Walking across bridge • Length of rope from cage: 23.65 m • Height of cage, swing point • Weight of cage: 477.5 Kg • Average male and dwarf weight • Video cage period: 12.9 s • Stop watch average between two swings
Calculations Ark-Length Ark-Length = Ark-Length = Ark-Length = Ark-Length =
Conclusion • Proven Correct • Time • Movie: 12.9s • Calculated: 9.76s • Difference do to air resistance • Force of swing
